"UN 131E JOSIAH K. LILLY, OF INDIANAPOLIS, INDIANA,

ASSIGNSR TO I'll-IE ELI LILLY AND 6 DISPENSING-BOTTLE.

Application filed February 21, 1913.

To all whom it may concern:

Be it known that I, Josmn K. LILLY, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Dispensing-Bottles, of which the following is a specification.

My invention relates to bottles and its object is to provide a construction of bottles whereby the liquid contents thereof may be dispensed directly from the bottle in the form of measured drops and in which the stopper of the bottle .is utilized as a regulating closure for the dispensing opening and as a plunger to force the liquid through the opening.

lVith these ends and others in view my invention is embodied in preferable form in the device hereinafter described and illustrated in the acoinpanying drawings.

In these drawings Figure 1 is a side view in elevation of a bottle embodying my improvements and showing the stopper seated and the dispensing opening cut off; Fig. 2 a similar view with the stopper plunger in position to permit the liquid to be dispensed through the opening and showing the bottle in horizontal position; Fig. 3 a side view in elevation of the stopper plunger removed from the bottle; Fig. 4 a detail enlarged vertical section through. dropper tube.

Referring to the drawings, 1 is a liquid container preferably in the form of a glass bottle and preferably of continuous cylindrical form throughout, except at the open end where the mouth of the bottle is slightly flared outwardly to provide a seat for the hen d of the stopper. A short distance below the open end of the bottle the same is provided with a laterally extending open tube 2 which is of the required diameter to permit a drop of predetermined size to be dispensed through the tube. Adapted to close the open end of the bottle is a stopper 3 of flexible material preferably cork, having a cylindrical head 4 of a slightly greater diameter than that of the body of the bottle and forming a member of sufficient size to be conveniently grasped to enable the stopper to be manipulated to move it in and out in the container. This head also serves to limit the inward movement of the stopper.

Specification of Letters Patent.

Serial No. 749,98

When the stopper is seated, its elongated body 5 extends within the container to a pointbeyond the opening of the dropper tube thus serving to close said opening and prevent the escape of the liqunid therethrough. This body portion 5 of the stopper is tapered outwardly, being smaller at the end adjacent the head for the purpose of permitting more easily the outward movement of the stopper when the same is to be manipulated to open the dropper tube.

In the operation of the device the stopper, when seated, serves to close the upper end of the container by means or" the head land to close the opening to the dropper tube by means of the long closure body 5. To dispense drops of liquid from the container, the latter is held in horizontal position with the opening downward and then by grasping the head l and pulling the stopper outwardly the closure body 5 is carried ou wardly suiliciently far to uncover the opening of the tube and then by applying a slight twisting motion with inward pressure to the stopper, the plunger body will. be pressed. agains the liquid so as to force the latter out through the tube in uniform drops. The body portion 5 thus serves as a plunger to force the liquid out in drops as well as a closure for the dropper tube.

Having thus described my invention, what I claim is:

1. A drop dispensing liquid container having an open end and having a'single opening only in the side of the container below said open end and having a flexible closure member provided with a head which seats against the outer end of the bottle and provided with a solid, flexible plunger body portion of a length sufficient to extend beyond the opening so as to close the same whereby the opening will be closed when the head of the closure is pressed to its seat and whereby the liquid in the container is adapted to be forced out a dropiat a time by the inward pressure of the plunger body against the liquid, substantially as described.

2. A. drop dispensing liquid container having an open end and having a single drop exit opening only through the wall of the container below said open end and having a closure member adapted to lit and completely close the open end of said container which member is provided with an my hand andseal at Indianapolis, Indiana, enlarged stop head and with an elongated this 29thday of January, A.
